IMPROVEMENT IN GOBN-PLOUGHS.

TO ALL WHOM IT MAY CONCERN:

Be it knownthat I, M. C. BUFFINGTON, of La Harpe, in the county of Haiieock, and State of Illinois, have invented a new and improved Corn-Plough; and that the following description, taken in connection with the accompanying drawings, hereinafter referred to, forms a full and exact specification of the same, wherein I have set forth the nature and principles of my said improvements, by which my invention may bedistinguishedi from all others of a similar class, together with such parts as I claim and desire to havesecured to me by Letters Patent.

This invention relates to a new and improved corn-plough or cultivator, and consists ina novel construction of the same, as hereinafter fully shown and described, whereby tl1e'di'aught-pole is elevated above the corn so as to prevent the same being broken down and injured, and a draught obtained which will admit of the draughtpole being balanced so as to avoid any undue pressure on the necks of the draught animals, while the ploughs are rendered capable of adjustment as circumstances may require. In the accompanying sheet of drawings- Figure 1 is a side sectional view of my invention taken in the line :b m, fig. 2. Figure 2, a front view of the same. Similar letters of reference indicate like parts.

A represents the axle of the machine, which is bent so as to have inclined sides a a gradually converging" toward each otherfrom their lower ends to the top, a horizontal portion, 6, being atthe top, to which the draught-pole B is secured by a bolt. The lower ends of the axle are bent forward, as shown at c, and have each a pulley, (1, attached, a similar pulley, 0, being secured on the draught-pole about over the top of the axle. In practice the pulley e is designed to be adjustable so that it may be moved further forward or backward, as desired.

C 0 represent the arms of the axle, on which the wheels D D are fitted loosely. These arms are secured to the lower parts of the axle A at the angles formed by the bc nt horizontal ends a, and it isdesigned in practice to have the arms attached to the axle by bolts passing through any one of a series of holes in the arms to admit of the latter being secured higher or lower in position, and further forward or backward, as occasion may require.

Itwill be seen, from the above description, that the wheels D D may be of medium diameter, and the draught-pole quite elevated, suflieiently so to clear or be above the corn, so that the latter will not be injured or broken down by it as the machine is drawn along.

Over the pulleys cZ (Z and e a chain or rope,.E, passes, the latter having a whiflle-tree at each end, to which a the horses are attached, and it will be seen that the pressure of this chain or rope on the pulley ewill, by

adjusting the pulley a further forward or backward, take all strain off the necks of the team; in fact, a drivers seat may be fitted on the rear part of the draught-pole, and the driver perfectly counterpoised. The machinc, therefore, may be used as a sulky-plough, if desired.

F F represent two plough-beams, which are provided with handles G and ploughs H, attached or appliedin the usual manner. These beams are attached to the front lower ends of the axle A, as follows: The front horizontal ends 0 e have each a rod,f, projecting inward from them at right angles, and on these rods tubes g are fitted loosely and secured by nuts or other device. Each tube has two vertical tubes, 7H1, attached to it, said tubes It not being attached to g at their centres, but somewhat out of centre, as shown clearly in fig. 2. The front ends of the beams F l have metal plates t'z'attachcd to them, one at their upper and the other at their lower sides, between which the tubes h are fitted, and a pin, j, passing through all;

By this means a universal joint connection is obtained, which admits of the ploughs being moved up and down and sideways.

Two tubes, h, are attached to each tube 9, in order to admit of the plough-beams being placed nearer together or further apart, as may be desired, and, in consequence of the tubes It being attached to the tubes g course, being higher when the longer portions of the tubes h are above the tubes 9.

out of centre, the beams may be secured in a higher or'lower position by reversing the tubes 7, the beams, of

The rods f are braced by bars or rods 70 fromthe rear end of the draught-pole B, and to the rear end of,

the draught-pole there are hooks Z by which the rear ends of the plough-beams may be suspended above the surface of the ground when the device is being drawn from place to place.

Having thus described. my invention, I claim as new, and desire to secure by Letters"Patent 1. The bent axle A, with the wheel-arms G and draught-pole B attached, as shown, in connection with the pulleys d d e and draught-chain or cord E, all combined and arranged to operate in the manner substantially as and for the purpose set forth.

2. The-attaching of the plough-beams F to the axle A by means of the tubes h g, the latter being fitted on rods f attached to the parts 6 of the axle, and the former secured by pinsj between plat-es z'iat the fi'ont ends of the plough-beams. Y I i A,

3. The brace-rods or bars is, connected with the ends of the rods f' and the rear end of the draughtpole 13, substantially as and for the purpose specified.

4. The combination of the axle A, lraught-pole B, brace-rods or bars k, and the universal joints which connect the plough-beanis with the axle, all being arranged substantially as and for the purpose specified.

M. C. BUFFINGTON.
